Geological Drilling Tube

Geological drilling Tube and oil drilling tube
To detect the underground rock structure, ground water, oil, gas and other mineral resources, we use drilling machine to dig a well. Geological drilling tubes and oil drilling tubes are the main equipments of a drilling machine. The machine includes double-tube core barrel, casing pipe and drill pipe. Due to the requirement, seamless steel tube for drilling need to work delve into the earth for thousands of meters. The operating conditions is extremely complex. The pipe need to endure various stress, and multiple mediums' wear and tear. All these factors makes the pipe must have enough strength, hardness, toughness and abrasive resistance.
